Background & Aim: To assess functionality status and surgical outcome of fenestration versus laminotomy technique based on Core Outcome Measures Index (COMI) in patients with lumbar disc hernia (LDH).Methods & Materials: Patients: A cross–sectional study was performed between January 2007 and April 2012. A total of 108 patients with a single–level disc herniation were asked to respond to the Oswestry Disabiltiy Index (ODI) and COMI at two points in time: pre– and post–operative assessments. The ODI and COMI were assessed comparing patients’ pre– and postoperative scores to determine the functionality status and surgical outcome.Results: The mean age of patients was 52.4 (SD=10.1) years who underwent fenestration (n=45) or laminotomy discectomy (n=63). The mean clinical follow–up was 27.8 (SD=3.6) months (range 24 – 37 months). Regarding COMI scores, all subgroup values showed statistical significance pre– and postoperative indicating improvements on the outcomes and functionality. The change in the ODI after surgery was strongly correlated with change in the COMI, (r=0.79; P0.001). The ODI score also was found to be statistically different between the groups in pre–and postoperative (P0.001) assessment. However, the functionality status rate was similar in both groups.Conclusion: The findings suggest that fenestration or laminotomy discectomy is an efficacious procedure for treatment of LDH. However, both methods are equally effective in surgical outcome.

In the crystal structure of the title polymeric compound, [C42H38N6O33Sr5.2(H2O)]n, five independent metal atoms (Sr1–Sr5) have different coordination environments. The S 1 and Sr5 atoms are nine coordinated and feature distorted tricapped trigonal–prismatic and capped square–antiprismatic geometries, respectively. The rest SrII atoms have eight coordination numbers. These units are connected via the carboxylate O atoms of mono– and di anionic forms of pyridine– 2,6–dicarboxylic acid, (pydcH2), and bridging water molecules that resulted in the formation of polymeric layers in 3–D. In the crystal structure, non–covalent interactions consisting of hydrogen bonds (O—H···O and C—H···O), – [interplanar distances of 3.413(2); 3.601(2) Å] and CO··· [O··· distances of 3.249(3); 3.275(3) Å] stacking interactions play an important roles in stabilizing the structure. The protonation constants of propane–1, 2–diamine (1, 2–pn) and pyridine–2,6–dicarboxylate ion (pydc)2–, the equilibrium constants for the pydc–1,2–pn proton transfer system and the stoichiometry and stability of this system with Sr2+ ion in aqueous solution were investigated by potentiometric pH titrations. The stoichiometry of one of the most abundant complexed species in solution was found to be the same as that of the crystalline SrII complex.
